Between 1936 and 1938, three very large Moscow trials of former senior Communist Party leaders were held, in which they were accused of conspiring with fascist and capitalist powers to assassinate Stalin and other Soviet leaders, dismember the Soviet Union and restore capitalism. These trials were highly publicized and extensively covered by the outside world, which was mesmerized by the spectacle of Lenin’s closest associates confessing to most outrageous crimes and begging for death sentences.
According to Joseph Stalin’s interpreter, Valentin Berezhkov, Stalin spoke highly of the Night of the Long Knives in 1934 and viewed Hitler as a “great man!” who had demonstrated “the way to deal with your political opponents”.
